This invention relates generally to an improvement in box car doors for railway freight cars and box bodies of motor vehicles a of the freight carrying type, of new and novel construction which will be understood from the description and drawings set out below.

It is an object of this invention to provide a box car door which has improved means to keep out water, dust and dirt and in addition will be strong and serviceable and easily operated, and which forms a protective door Which will not easily come loose or get out of order.

It is also an object of this invention to provide a box car door of the type described which will efficiently and efiectively protect the contents of a box car particularly on long hauls, during which trouble is frequently developed in the ordinary type of box car doors which results in expensive delays for repairs and replacements.

These and other objects of the invention, its nature, and its combination and arrangement of parts will be readily understood by anyone acquainted with the art to which this invention relates upon consulting the following description of the drawings in which:

Figure 1 is a general front elevational view of a portion of a box car showing incorporated therein my improved door.

Figure 2 is a transverse vertical cross section approximately on the line 2-2 of Figure 1, and

Figure 3 is a horizontal cross sectional view taken approximately on the line 33 of Figure 1.

Referring in detail to the drawings the numeral 5 designates generally a conventional box car having a door opening 6 over which is suspended a hood or door track protector 7. A slidingdoor 8 carries rollers 9 on each side of an upstanding flange 10 attached to the upper end portion, and on the outside of the door as at 11. The rollers 9 are sup- 45 ported in the tubular track which is slotted longitudinally in its under side to permit the passage of the flange 11, and position the rollers to run on the said bottom of the tubular track 12, one on each side of the slot there- 50 in. Supported upon and outward of the up- 1931. Serial No. 531,811.

standing flange 11 is an upstanding hook 13 which has its hooked portion directed outwardly and downwardly to engage over but not to contact, a hook portion 14 upwardly and inwardly formed on the lower edge of the door and runs downwardly and then under the door as at 17, and then has a hook portion 18 upwardly directed to hook behind the runner 19 secured to the body of the car, whereby the lower end of the door is retained from lateral movement from the car body, and guided in its travel to the various positions in which it may be adjusted.

Reference to Figure 3 will disclose that on each. side of the door opening 6 and attached to the door post on each side of the door opening is an L-shaped bracket 20 which is attached to the face of the door post, and then reaches laterally to the outside of the car body and then is directed in a direction away from the door opening and in abutment with the outside of the car body. A hook, formed by a flat return bend 21 and a round return bend 22 engages a hook in an exactly similar bracket 23 on the contiguous end of the door which is adapted to so engage, when in closed position.

On an opposite door post of the opening is disposed another bracket 24 very similar to the bracket 20. The bracket 24 as seen in Figure 3 has a longer portion 25 engaged with the outside of the car body, or rather is supported outwardly from the side of the car body by a support 26. The bracket 24 has a double hook formation 27 extending laterally of the terminal of the portion 25 of the bracket. The end of the door contiguous to the bracket 24 when in closed position is provided with the bracket 28 secured to the outside of the contiguous edge portion thereof and inwardly directly as at 29 where a hook formation 30 is adapted to engage both of the hooks 27.

Since the brackets 20 and 24 extend the full height of the door opening, and v cooperate with the brackets 23 and 28 on the door, the

the formation of the hook 13 cooperating and lower edges of the door are rendered door when in closed position is practically proof against the entry of dirt, dust and the contents of the car is protected against contamination or other injury by substances which ordinarily are not prevented from entry therein by other types of box car doors. It Will be observed that the bracket 15 likewise protects the doorfand together with with the formation of the hood 7, the upper practically dirt and dust proof. Thus all of the points of entry of dust and dirt'and other contaminating substances are cut off in a practical manner, which at the same time givesan added ruggedness and operativeefficiency to the door which it would other.- wise not have were'it constructed in the conventional manner and suspended for cooperating with the door opening in the presently practiced methods.

v The numeralSl denotes one of a pluralit of straps or hands having the quadruple bent portion 32 and supported on the side of the car and particularly well shown in Figures 1 and 2, for constituting limit stops for the movement of the door in its travel from closed position;

v The brackets, the tracks, the hood, and the guide runner 19 maybe constructed of suitable ironor the like-though it is notdesired to limit the invention to any particular material or method of-assembly or attachment of one part to the other. It is to be definitely understood that I do not desire to limit the application of this invention to the particular modification set out herein to illustrate the principles thereof and any change or changes maybemade in material, arrangement and combination of parts consistent with the spirit and scope of the inyention. Having thus described my invention what I claim as new is: I I

1.,A box car door of the slidable type described comprising a conventional door body plate attached to the upper part of the door, a hooked formation on the upper edge thereof b for engaging in said channel formation, said hood being extended to coverthe door when in opened position. V

2. The combination with a box car hav ing a portion of its floor extended through its door opening, of a sliding door adapted toabut the outward edge of said portion of the floor when in closed position, a verticaldou-- ble channelled plate secured adjacent one side of the door opening carrying a lateral-flange secured within the opening, a vertical single channelled plate secured adjacent the opposite side of the door opening carrying a lat eral flange received within the door opening, said platesbeing extended substantiallytli -e full iengthofthe dooraopening, a double channelled bracket secured extend from one end of the door'for cooperation with said double channelled plate, a singlechannelled bracket secured to extendfrom the opposite end of the doorfor cooperation with the said single channelled plate, when the door is in. closed position, the channels of saiddouble adapted to be moved into closed and opening 7 position with respectrto a door opening'of a box car, comprising plates attached to and extending the length of the top, bottom, and side edge portions of the door and projecting therefrom and, arranged to cooperate with channeled flanges attached about the door opening so as to seal theopening against-the ingress of moisture and foreign particles whenthe door is inclosed position,-and rollers on each side of a vertically risingflange on the upper end of the door for riding 7 upon the bottom within a tubular track carried over the door opening for supporting 7 Q the door, the bottom having a slot for accommodating said Vertical flange, and, a
